python实现统计字符类型

#字符串处理统计类型
def my_func(*str):
    list_num = []
    list_big = []
    list_small = []
    list_qt = []
    str = input('请输入一个字符串')
    for j in str:
        elif ord(j) > 47 and ord(j) < 58:
            list_num.append(j)
        elif ord(j) > 64 and ord(j) < 91:
            list_big.append(j)
        elif ord(j) > 96 and ord(j) < 123:
            list_small.append(j)
        else:
            list_qt.append(j)
    a = len(list_big)
    b = len(list_small)
    c = len(list_num)
    d = len(list_qt)
    print(str)  # 输出一次你所输入的字符串
    print('大写%d个，小写%d个，数字%d个，其他%d个' % (a, b, c, d))  # 统计各类字符个数
    list = [a, b, c, d]
    print(tuple(list))
